My experience is the biggist killer is the noise/ripple, and the voltage sag with load, which is made worse by overly long leads, too thin a wire guage and crappy connectors. Hence the move away from the microUSB connector (1.8A max rating and crappy connectors at the best of times), and bumping the voltage up to 5.2v to overcome voltage sag.
